Step by step

1. Discovery · Same Day

   Document Changes Before Work Starts

   The moment you or your contractor identify any change to the original scope, stop and document it before proceeding. This includes upgrades, modifications, unforeseen conditions, or design adjustments. State clearly what's changing, why it's changing, and what the original plan specified. Insist on this documentation even for changes that seem minor or that the contractor suggests can be handled informally.

   Tip: Text messages and verbal agreements are not change orders, no matter how detailed or friendly the conversation.
2. Pricing · 1-2 Days

   Break Down Every Cost

   Require the contractor to provide specific costs for materials, labor, and any subcontractor fees related to the change. The pricing should break down to line-item detail, not a single lump sum. If the change involves removing something already purchased, clarify whether you'll receive a credit. Compare the pricing against your original contract rates to ensure consistency in labor charges and markup percentages.

   Tip: A change order that costs more per square foot than the original scope of similar work deserves scrutiny and explanation.
3. Scheduling · Same Week

   Map Downstream Schedule Effects

   Determine how the change affects the project schedule and the order of subsequent work. Some changes push completion dates because they require additional trades, specialty materials with lead times, or permit modifications. Others might actually accelerate the schedule. Get the contractor's written assessment of timeline impact and how it affects other scheduled subcontractors or material deliveries.

   Tip: Changes early in a project have cascading effects, while changes near the end usually affect only completion date.
4. Review · 1-3 Days

   Negotiate Like a Contract

   Examine the written change order for completeness, checking that it includes description, pricing, timeline, payment terms, and reference to the original contract number. Question anything unclear or that seems disproportionate to the work involved. Negotiate if the pricing seems inflated, the timeline impact excessive, or the scope description vague. This is a contract amendment and deserves the same attention you gave the original agreement.

   Tip: Never sign a change order under pressure with the contractor standing over you waiting to proceed immediately.
5. Payment Terms · Before Signing

   Lock Down Payment Terms

   Clarify when payment for the change order is due and whether it follows the same draw schedule as the original contract or requires different terms. Some contractors expect change orders paid in full upfront, others add them to the next scheduled payment, and some create separate invoicing. Make sure the payment approach is explicitly stated in the change order document and that you're comfortable with it before signing.

   Tip: Large change orders exceeding ten percent of the original contract value should generally follow a draw schedule, not lump-sum advance payment.
6. Documentation · Ongoing

   Track Every Modification Centrally

   Create a spreadsheet or document that tracks every change order with columns for date, description, original estimate, approved cost, payment status, and completion status. Update this log immediately when each change order is signed and again when the work is completed and paid. This running record becomes essential for tracking total project cost, managing cash flow, and resolving any end-of-project disputes about what was agreed versus what was delivered.

   Tip: Your log should show cumulative change order total so you can see at a glance how modifications are affecting your overall budget.
7. Inspection · Upon Completion

   Verify Work Matches Scope

   When the change order work is finished, photograph it and inspect it against the written scope before authorizing payment. Verify that materials match specifications, workmanship meets standards, and any aspects of the original work that were supposed to be modified are actually complete. Mark the change order as complete in your log only after this verification, and note any deficiencies that need correction.

   Tip: Photograph the work before it's covered by subsequent construction phases, especially for structural or in-wall changes.
8. Close-Out · Final Week

   Reconcile Everything Before Final Payment

   Before final payment, review your change order log against all invoices and the contractor's final bill. Verify that every signed change order is accounted for, that nothing unauthorized appears in the billing, and that all change order work was completed satisfactorily. This reconciliation often reveals billing discrepancies that are far easier to resolve before final payment is released than afterward.

   Tip: Expect your total change orders to add ten to twenty percent to most renovation contracts, a normal range for unforeseen conditions and owner-requested modifications.
